READ AND SAVE THESE INSTRUCTIONS IMPORTANT SAFEGUARDS Follow basic safety precautions when using your smart air fryer toaster oven. Read all instructions. Key Safety Points • Do not touch hot surfaces. Use handle. • The outside of the oven, including the door, is hot during and after use. • Always use heat-resistant gloves, pads, or oven mitts when handling hot materials, and when placing items in or removing items from the oven, including trays, racks, accessories, or containers.
While Cooking Plug & Cord • Do not place oversized foods or metal utensils (except for Cosori accessories) into your oven. • Do not place paper, cardboard, or non-heat-resistant plastic into your oven, or any materials which may catch fire or melt. • To avoid overheating, do not use metal foil in the oven unless directed. Use extreme caution when using foil, and always fit foil as securely as possible. If the foil contacts the oven’s heating elements, this can cause overheating and risk of fire.

We especially recommend using the Shake Reminder with the Air Fry function (see page 16). • The Shake Reminder will appear halfway through cooking time.
CARE & MAINTENANCE Clean oven accessories (including trays, etc.) and oven interior after every use. Cleaning the Accessories Note: Note: After each use, slide out the crumb tray and discard crumbs. • The walls on the inside of the oven have a nonstick coating for easy cleaning. • Do not use abrasive cleaners, metal scouring pads, or metal utensils on any part of the oven, including trays and other accessories. These will scratch or damage their surfaces.
TROUBLESHOOTING Problem Possible Solution The oven will not turn on. Make sure the oven is plugged in. Food is not completely cooked. Increase cooking temperature or time. Decrease cooking temperature or time. Food is overcooked or burned. Make sure food items are not too large and are not touching the heating elements. Preheat the oven manually by using the Preheat function (see page 15). Food is cooked unevenly. Make sure food items are not too closely packed into a tray, rack, or other container.
VESYNC APP TROUBLESHOOTING Problem Possible Solution During the setup process, you must be on a secure 2.4 GHz WiFi® network. Confirm that the network is working correctly. Make sure the WiFi password you entered is correct. Why isn’t my oven connecting to the VeSync app? Turn on Bluetooth® on your phone (for Android™ users, make sure Location is turned on as well). Make sure your oven and phone are within 30 ft / 10 m of each other.
